Title
Statistical Alloy Design of Precipitation hardened Nickel - Base Superalloys
최주Ju Choi, 이종근Chong Keun Lee, 최승주Seung Joo Choe
Abstract
Trials were made to develop gamma prime precipitation hardened nickel-base superalloys which have both excellent creep rupture strength and hot corrosion resistance. The factors which influence high temperature characteristics were expressed a function of alloy composition by means of multiple regression analysis. Setting certain conditions on the factors, alloy composition was calculated with use of the computer. The alloys developed by this method are proved to be excellent in creep rupture strength and sulfidation resistance.
